I've used ps2 mice with ps2->serial adapters loads of times with pcs, so how is it different with this? if the mouse finally has a serial connector and it works on a serail port on the pc why does it not work on the mroocheck?
That is what I originally thought, and I ended up banging my head against a wall for a long time. I had a plain old PS2 mouse and a half dozen PS2 to serial adapters. None of them worked on the Amiga with Mroocheck, and none of them even worked on the Windows PC with that adapter connected. I thought the PS2 to serial adapter would do the trick and convert it, but it didn't.
The reason, I learned after some research, is that PS2 mice use a different protocol than serial mice, and a simple converter won't do the trick. You need a mouse that supports both protocols. I imagine that's what these PS2 to serial adapters were really designed for.
Most mice I've seen lately are either PS2 or USB. You'll be better off buying yourself a PS2 to Amiga adapter or going the USB route. I ended up getting a PS2 to Amiga adapter, and it works just fine now.
